MNLinda, about the excellent sandhill crane pic, I think it might be the one I posted yesterday. All thanks to the camera operators! Feel free to use it any way you choose, and I'm pleased that you remarked about it.
I haven't paid much attention to people sounds from DNN, but it is a working farm, so they use tractors in the fields, and power saws, etc. from time to time. The eagles and other critters don't seem much bothered. Have you ever been watching when a young eagle has a close encounter with one of the cows? Hilarious. Might be in an archival video.
